So I got Radeon 6800 XT working on Ubuntu 18.04.5 LTS but it wasn’t hassle free, given the card is too new To get it working, you’ll need the following: Mainline kernel 5.11+ or newer (5.13+ recommended) Newer firmware Kisak PPA Optionally 5.13 patch for Full RGB option (discussion) Update: […]
I’m adding this as a reminder for myself. To get ASAN to work with Ignition Gazebo we first need to modify CMakeLists.txt to build with ASAN. For every module (e.g. ign-gazebo, ign-rendering, ign-gui, etc) you wish to have full ASAN analysis, write this at the top of each CMakeLists.txt: Running […]
I finally found an explanation that worked on my (non-tech-savvy) friends using an analogy. How Bitcoin works, consensus, and why ‘mining’ rewards money. Why on Earth having a computer running all day earns money? My friends struggled with this concept. This explanation was very well received. So I thought I’d […]
By default RenderDoc only downloads resources used by the frame being captured. Resources not used during that frame are not saved. Unless ‘Ref. All Resources’ is enabled, that is. I recently fixed a bug in Ogre where Ref. All Resources would randomly corrupt GPU memory after capture; both in my […]
So I saw these tweets earlier today: Horizon Zero Dawn has been fun.Tells me I have an old driver. Still runs. Takes 30 minutes to compile shaders. I watch the intro cut scene. I think. Better to update the drivers. I quit. Update drivers. Start the game again.And now we’re […]
So… it’s hard to ignore yesterday’s announcement of Unreal Engine 5 with a very impressive demo There’s a lot of chatter about how they’re doing and like Angelo said, proving that something is possible suddenly inspires other people to come up with their own ideas. So I am going to […]
So… I made a joke that became more popular than I expected. I thought it was going to be a niche joke only graphics programmers would understand, but as it got popular I got to realize many others would get it too: Substance Painter artists, Adobe users, Blender/Maya/etc users rendering […]
Due to various reasons, I’ve had to work with Unreal Engine 4.Since my main development environment is Linux, the quality was amazingly fantastic but there were a few rough edges. Since Wiki editing is currently disabled, I am posting it here to improve quality of life for Linux devs having […]
memtest86+ is not available on UEFI.memtest86 (a non FOSS product with a free and a commercial option) is often in the answers as the alternative. However the only option you have is to download it, and format an entire USB stick and boot for it. Well… that’s not necessary! We […]
Because Ogre uses Mercurial hosted on Bitbucket, and Mercurial is being removed, this guide is aimed to helping our users to migrate as painless as possible. Git differences We need to explain a few differences from hg to git. If you’re a git expert, you can skip this section. The first main difference is that hg treats the repo history as immutable. Only advanced operations (which must be explicitly enabled) can manipulate history. And doing […]
